I try to use ConsensusClusterPlus to subgroup my samples. This package will generate a random seed number and put the seed number in the output log file. However, I found I couldn’t repeat the result with the seed number even with the domo dataset. The code and result I get is listed below.

The other question is about the reproducibility. Using my own data, the output from manually assigned a seed number (seed = as.numeric(Sys.time())) is very different from the output from randomly generate a seed number. All the “non_seeded_outputs” I get are very similar if I didn’t give any seed number (with bootstrap=1000). All the “seeded_outputs” I get are also similar to each other (also with bootstrap=1000). But the “non_seeded_outputs" and “seeded_outputs” are very different. :(
